No roots!

[paperchaser825]

Are there any ways to induce or help rooting in a dwc? Net pot is 8 in. medium is rockwool in hydroton. Water level is right under the net pot and the aeration is sufficient and running 24/7. Any ideas???

:hippy:

same thing is happening to me actually

i had the water where you have it and i lowered it a bit in hopes the roots will go searching, but still nothing

the plant has been growing well for about 2 weeks now but still no sign of roots....i suppose until my plant stops growing it isnt really a problem

Anyone? Could be my ridiculous impatience, but I am at the same place also...almost 3 weeks into growth and no roots for my super mix of nutes

Could heating the water until the roots start reaching help? (root streches for the warmth??)

OK, I will try to decifer. Number one, you mentioned, you're using rockwool and hydroton. Those are two COMPLETELY different mediums. Try this, fill a 6" net pot full of rockwool, and fill another net pot the same size with hydroton. Lets just suppose you have a young plant in each one. Now pour a quart of water over each pot and wait and see what happens. Within 24 HOURS your plant depending on its size will be dead. The plant in rockwool will still be alive 10 or 12 DAYS. This shows the ability of rockwool to hold water is much different than the clay pellets.

I can tell you that a clone rooted in a VERY SMALL cube of rockwool placed in a netpot filled with hydroton, will not thrive as well as a clone placed in hydroton without the rockwool. Why? Using the watering schedule for watering hydroton, or DWC, the cube will never get enough oxygen simply because its getting too much water. I occasionally root clones in rockwool cubes but use mainly an aero cloner. I try to remove as much (sometimes all) of the rockwool before placing the girl into the net pot with hydroton. If I leave the rockwool on the plant and place it into the net pot with hydroton, the roots will not thrive within the area until it develops roots above or below the rockwool cube.

Hope this helps

Hand feed them through the top of the pots until a nice handful fall through and watch them take off!

And roots = only cold water :stoned:

Ok, i have the rockwool in an 8 inch net pot the rockwool is like 5 inch cubes...the rest of the pot that is not rockwool is hydroton...so i should water where the hydroton is?

That's your problem. Cubes, ESPECIALLY Large cubes like yours are not meant to be in a DWC, you will drown your plants, or at the very least they cannot thrive. When there is that much rockwool it will never get a chance to dry so that your plant gets oxygen.

You will either have to either reduce or eliminate the rockwool from the plant, or set your plants on a tray the way they are, and feed them water/nutes by hand. I would not water them more than once a day or even every other day.

Cold water no, tepid water yes, cold water will be a shock to the roots.

Water temp should be around 23'C
